GS4A034991GT

GS4A034991GT Description

The GS4A034991GT from TT Electronics/IRC is a high-precision 4-resistor isolated network in an 8-pin narrow SOIC package, designed for demanding electronic applications. Featuring a 4.99KΩ resistance value with a tight ±2% tolerance and a low ±25ppm/°C temperature coefficient, this thin-film resistor network ensures stable performance across a wide temperature range (70°C to 125°C). Its ceramic case style and gull-wing termination provide robust mechanical and thermal stability, making it suitable for surface-mount (SMD) PCB assemblies. With a 100V maximum voltage rating and 0.1W power dissipation per resistor (0.4W total), it balances compactness with reliability.

GS4A034991GT Features

• Precision Thin-Film Technology: Delivers low noise and high stability for sensitive circuits.
• Isolated Circuit Design (ISOL): Each resistor operates independently, reducing crosstalk in multi-channel systems.
• High-Temperature Resilience: Rated for 125°C max operating temperature, ideal for harsh environments.
• Compact SOIC Package: 4.9mm × 5.99mm footprint with 1.45mm profile, saving board space.
• Strict Tolerances: ±0.1mm length/height tolerances ensure consistent manufacturability.
• Non-Automotive (PPAP No): Optimized for industrial, telecom, and instrumentation use.

GS4A034991GT Applications

• Signal Conditioning: Precision voltage dividers in data acquisition systems.
• Medical Electronics: Isolated feedback networks in diagnostic equipment.
• Test & Measurement: Calibration circuits requiring low TCR drift.
• Power Management: Current sensing in DC-DC converters.
• Industrial Controls: Robust resistor networks for PLCs and motor drives.

Conclusion of GS4A034991GT

The GS4A034991GT excels in applications demanding high precision, thermal stability, and compactness. Its isolated thin-film resistors, ceramic construction, and SOIC-8 form factor make it a superior choice over bulkier or less stable alternatives. While not RoHS-compliant, its performance in industrial and professional electronics justifies its niche. Engineers seeking reliable, space-efficient resistor networks for moderate-power, high-accuracy circuits will find this model ideal.
